In 1666 there was no organised fire brigade. Firefighting was very basic with little skill or knowledge involved. Leather buckets, axes and water squirts were used to fight the fire, but had little effect.

The maps, which are primarily a predictive tool, will impact individuals and jurisdictions by determining where certain building and landscaping rules will be enforced.

Map allows transforming collections by applying a function to each element, resulting in a new collection of the same structure, while flatMap flattens nested structures into a unified collection.
